The NFC TagWriter by NXP stores contacts, bookmarks, geo location, Bluetooth Handover, SMS, Mail, text messages and many more to any NFC-enabled tags as well as to items like posters, business cards, watches and many more containing NFC-enabled electronics. Once data has been stored the application allows also reading and viewing the programmed data including options to launch applications automatically based on the contained data.

NOTE: Installing TagWriter on a non-NFC enabled phone is enabled now but it does of course not allow you to actually program tags. Anyhow, you can now prepare NFC data sets e.g. on a large screen device and then share them with an NFC enabled handset to actually make use of them. Besides that you can catch a pre-view on what you could do with a handset supporting NFC.
Please contact us at nfcapp.support@nxp.com if you have problems. We will continue our efforts to add new features for your benefits and we work hard to provide a feature rich application ahead of other apps available in the market.

Next to the creation and storing of NFC data sets the NFC TagWriter by NXP also allows to automatically launching applications based on the data read from NFC-enabled tags and items containing NFC-enabled electronics.
The following NFC data sets are supported to launch applications:
- Contact (vCard) to import data into the address book (Contacts)
- Bookmarks (URL) to open a given web address
- Plain text to display simple messages directly on the screen
- SMS (SMS URI) to create a new message
- Mail (Mail URI) to create a new mail message
- Telephone number (TEL URI) to start a call
- Bluetooth to pair and connect devices
- WiFi to connect to WiFi Networks
- Geo location to open a given destination- File URI to open a file on the device, including file picker UI
- URI to create any kind of URI, also those not directly supported by the NXP TagWriter

It supports a series of configuration options adapting the application to your own needs and preferences.

The application fully supports the NFC Forum Type 1 Tag, Type 2 Tag, Type 3 Tag as well as Type 4 Tag portfolio. This includes a whole range of NXP and third party NFC-enabled contactless IC products like MIFARE Ultralight, MIFARE Classic, MIFARE DESFire, NTAG 21x, NTAG I2C,  ICODE SLI & many others.TagWriter supports any NDEF pre-formatted tags for all NDEF operations but formating to NDEF feature is limited only to NXP Tags.

Please help us to improve and provide “crash report” and/or contact us via nfcapp.support@nxp.com. This helps us to detect, analyze and provide fix for the ICs that have not been verified to work and so may cause problems or unexpected behavior on use.
